Refine Finna Metadata

Source: R/refine_metadata.R
refine_metadata.Rd

The refine_metadata function cleans and standardizes Finna metadata by:

  • Validating Required Fields: Checks for the presence of key metadata fields and returns NULL if any are missing.

  • Handling Missing Values: Replaces NA values in critical fields with descriptive placeholder text (e.g., "Unknown Title").

  • Selecting Relevant Fields: Keeps only the following fields for streamlined analysis:

    • Title: The title of the resource.

    • Author: The creator or author of the resource.

    • Year: The publication or release year.

    • Language: The language of the resource.

    • Formats: The format(s) of the resource (e.g., Book, Audio).

    • Subjects: The subject keywords or classifications.

    • Library: The owning library or institution.

    • Series: The series or collection the resource belongs to.
